INTERQHANGEABLE JOURNAL FOR- TEXTELE FLUTED ROLLSm Application filed November This invention relates to spinning mac-hincry, and particl'darly to the fluted rolls thereof. M

The lower rolls" of spinning machmes which carry fluted bosses are usually made in sections, each section carrying upon a plurality of fluted bosses and the sect-ions being joined by a neck which forms a ournal bearing for the series of rolls and which is formed beyond the journal bearing with a square end adapted to fit within a square or many-sided socket formed in the adjacent end of the next adjacent roll section. Each of these necks, as before remarked, is pro vided with a journal bearing rotating within a roll. stand, andwhen lZ-llQJOUlTDitl bearing of a section becomes WOIIIllt 1S necessary that tshall be renecked, which means thatithe sec.- tion must be removed from the rollstand, sent to a machine shop, the neck must be sawed off adjacent. the junction of thejournal portion with the body of thesection then the end of the bodyf sectionwmust be bored out, and a new neck haying a ournal portion and a squared portion must be driveninto,

this bore until a drivingfit is secured This is a more or less expensive operation andit not very satisfactory for the reason that it difficult to get a p rfect drive lit between the new neck and the body of the secv tion and one that willnotperfnit the neck to,

become loose. j

The general ob ect of my nvention 1s to provide an interchangeable ournal,iw1th a fluted rolls,- which journal may be readily in-,

sorted into the extremity of the roll section or removed if necessary.

A further objectis to provide aninterchangeable journal which has screw-threads whereby it may be engaged with a screw threaded bore extending longitudinally into the section to be repaired, these screwthreads being so directedthat the rotation of the rolls in thespinning machine will'cause the interchangeable journal to tighten up within the'bore of the section so that there is no-chance for the journal to become loose therein.

A still further object is to provide a preferable form of interchangeable journal which is formed alike on both ends so that it will have screw-threaded engagement and a tapering fit within the adjacent ends of two sections of the roll shaft, thus permitting the journal to be readily removed from between 7, 1925.

the sections and a new journal inserted at any time and doing away with any chance of A lost motion or wear in the connection between the journal and the adjacent sections of the roll shaft. i

' Other objects will 'appear in the coursc of the following description.

My in ention is illustrated in the accompanyung drawlng, wherein Figure l isan elevation partly in section of one form of my interchangeable journal and allied roll sections;

Figure :2 is an elevation of the form of the interchangeablejournal shown in Figure *1; Figure 3 is an end elevation of Figure 2; Figure t is a sectional view of another for-mot interchangeable journal;

Figure is an elevationithereof; Figure 6 is a fragmentary View of the roll stand with the journal in place. 7

Referring to this drawing, and iparticularly to Figure l, A and designate two ad acent sections of a roll shaft, these sections of the roll shaft having upon them at ntervals the .tluted bosses The section B is illustratedas formed as a female member providing the longitudinally extending socket 10 and a circularcountersink 11 at the forward end of the socket. This is the ordi nary mannerof forming the section B. l The ordinary manner of forming the section A l is provide the end of the section with a cylindrical ournal portion and a square male vmember which will fit within the socketlth combination screw and taperfit tor textile 1 There is great likelihoodof play between the male ,menibenand the socket 10 and if there" is any-playthere is bound tobe wear.- This, however, 15; the standard practice today.

It now the ournal portion of theshaft should wear, the journal portion is cut off i on the linelw -as andithe shaft is bored toprovide the interiorly screw-threaded bore 12, the outerend of: this bore being out= wardly flared, asata13, and an intei 'change-.g

able journal, as shown in FigureQ, is then used comprising the cylindrical bearing portion let, the male portion 15 which is square in crosssectionto fitjwithin the socketldthe.

screw-threads 17 and to hear more and more tightly against the tapered portion 16 and thus practically lock the ournal 14 upon the shaft section A. Of course, the extremity of the journal 14 fits loosely within the countersunk portion 11.

In Figure 5, I show another embodiment of my invention in which the journal is formed with a journal portion 18 cylindrical in crosssection, oppositely disposed tapered portions 19 which taper inward and away from each other, and screw-threaded nortions 20 at opposite ends. In this case both of the shaft sections A and B are formed with the screwihreaded bores 12 and the flared or conical entrance nortions 13. The journal is screwed into engagement with the opposite, interiorly screwthreaded sockets of the shaft sections, and the normal rotation of the roll shafts A and B will cause the roll shafts to screw inward on the screws 20 until the conical. portions 15.) of the journal tit tightly and have wedging engagement with the flared sockets 13 of the roll sections.

It will be seen that I have provided means which may be used either on old roll shaft sections requiring repair or which may be used on new roll shaft sections where the sections are formed at their adjacent ends with the screw-tln-eaded bores 12 and the.

flaring sockets 13. It will be seenthat these journals are interchangeable and may be used anywhere along the roll shaft and that by using these interchangeable journals it is not necessary to take out the roll shaft section and send it to the repairer but that a mill having my improved journals in stock may readily remove a worn journal and put a new journal in place at a small expense.

The construction shown in Figures '1 and is preferable to that shown. in Figure 2 inasmuch as there is a chance for wear be tween the male member 15 and the socket 10, but all mills are provided with the section B having the sockets 10 and, therefore, unless the mill is to be newly equipped with the sections A and B constructed as in Fig ure 1-, it is necessary to provide interchangeable journals which will lit in the female members 10.

It will be seen that this device is simple and eliminates very great expense. It is difficult to cut off a worn journal from the end of a shaft and substitute a new journal therefor by drilling into the end of the shaft and forcing the new journal into place and,

as a. matter of fact, a very powerful hydra ulie press must be used for this purpose and even then it is oftentimes necessary to pin the inserted end of the journal to the adjacent end of the shaft to prevent any lost motion. It is to be understood that this journal is applicable not only to spinning machinery but to all spinning and card room textile tinted rolls.

I claim l. A detachable and intcrchangeable journal for use in joining fluted textile rolls comprising a medially disposed, cylindrical journal portion having a uniform diameter throughout its length, inwardly tapered portions extending from opposite ends of the journal portions, and having longitudiluilly extending screw-threaded extremities.

2. The combination with two spinning rolls, each roll having an inwardly extending, screw-tlu'eadcd bore at one end and the bore being outwardly flared and unscrewthreaded adjacent the outer end of the roll, of an interchangeable and detachaljile journal for connecting said rolls formed to provide a cylindrical, medially disposed journal portion of uniform diameter throughout its length, tapering portions extending centrally and hmgitudinally from the journal portion, and screw-threaded extremities fitting the screw-threaded bores of the rolls, the screwthreads 011 the extremities being inclined in such direction as to cause them to screw into the screw-threaded bores of the rolls when the rolls are rotating under service conditions. i

3. The combination with two spinning rolls, of a relatively short journal member disposed between the two rolls and locking the two rolls together for unitary rotative movement, said journal member having a middle journaled portion, the extremities of the journal member being formed to have detachable locking rotative engagement with the adjacent ends of the spinning rolls.

4:. The combination with a. plurality of drawing rolls, of relatively short journal members connecting and rotatively locking the adjacent ends of each pair of rolls to each other, each journal member having a middle journaled portion and having its extremities formed to have detachable looking rotative engagement with the rolls for common rotative movement therewith.
